Well the thing is, you can't connect to your desktop via wireless if your desktop has no wireless card installed in it. So in short I believe that you want your desktop connected via wired through the router so you can have your laptop on wireless. If your router is wireless with no ports for cabled connection then you should connect like this: Wall -> Ethernet Cable -> Modem -> Ethernet Cable -> Router ----------------------------------|---------------------------------| --------------------------Ethernet cable---------------------Wireless ----------------------------------|---------------------------------| ------------------------------Desktop-------------------------Laptop If your router IS wireless WITH ports you should connect like this: Wall -> Ethernet Cable -> Modem -> Ethernet Cable -> Router -------------------------------------------------------------------/\ ------------------------------------------------------------------/--\ ----------------------------------------------------Ethernet cable--Wireless ---------------------------------------------------------/------------------\ ----------------------------------------------------Desktop--------------Laptop If both these ways fail PM me.
